Microsoft Access and Dataverse for Teams, slow linked table

(0) ShareShare
ReportReport
Posted on by 9

Hi everyone! This is my first time to post a question here on the Power Apps community.

I've been developing a Microsoft Access solution that uses Dataverse for Teams as the backend, and I'm using linked tables to gain access to the backend data. Out of twenty (20) tables, I have three (3) transaction tables that contain a significant amount of data: 4K+, 4K+, and 13K+ respectively.

 

Microsoft Access does fine when I open the first two tables and jump from the beginning of the table to the end, using arrow keys. But when I do the same to the 3rd table, which by the way only contains ten (10) fields or columns, it freezes when I attempt to jump to the very end of the table. I thought I could get around this by scrolling down through each row one at a time, but even when my cursor has reached only the 200th row of the table or so, Access starts freezing, and it remains that way for more than 10 minutes, so I just close Access by force when that happens.

 

I thought this behavior would only happen when I was opening the linked tables directly, but unfortunately this same behavior happens when I query the linked table (the 3rd one) using SQL.

Thinking this was an issue about having too many records, I tried testing Dataverse for Teams and created a table with only two (2) fields (an ID, and a string value), with more than 40K+ records. Surprisingly, I can access this on Microsoft Access via linked tables and I can jump to the very end of the table after the linked table freezes for only less than 20 seconds.

 

Lastly, I tried linking to the Dataverse for Teams table with issues using a new Access database, but unfortunately it suffers from the same slowness.

 

I would love to hear your thoughts on this. Thank you!

    I just wanna add that in my experience, Microsoft Access can link to SQL Server tables and views hosted remotely on AWS accessed via VPN, and Microsoft Access has no trouble loading all millions of records to its linked tables. It takes time, like 2 to 3 minutes or so, but not extremely slow to the point of being almost unusable.

     

    On the other hand, my experience with Dataverse for Teams and Microsoft Access so far hasn't been great. But I'll try creating a new table and importing the same data set there. I'll update this post as soon as I get results.

    Columns:

    Text 1 (as primary key)
    Text 2 (40 characters)
    Text 3 (40 characters)
    Text 4 (40 characters)
    Date (date only)
    Decimal 1
    Decimal 2
    Choice (yes/no)

    No relationship with other tables
    13,000+ rows

    I replicated the same table structuer and data on Dataverse itself (not Dataverse for Teams this time), using the fields I listed in my previous comment and populated the table with more than 13,000 rows, and I get the same behavior. Once I scroll past the 300th record, the entire table and Microsoft Access freezes.
